IMPROVEMENT AlN BLIND-STOPS.

Specification formir f part of Letters Patent No. 168,634, dated January12, 1875; application filed f July 21,1874. Y

To all whom it may co'cer'n:

Be it known thatl I, ALFRED ToWNsEND ELFQRD, of Oakland, inthe count-yof Alameda and State of y California, have invented certainlmprove'mentsin Inside Blinds for Windows, of lwhich the following is a specifi i non0f inside blinds for windows by nl@ combination oi' slats having longtenons or pins, side grooves, and sockets, with rod and lockknob,combined and operated as will be hereinafter more fully explained,reference being -V had to the accompanying' drawings, making part ofthis specicat-ion.

Figure 1 is a front elevation, showing a sectionof slatted blind, with asection cut out of the frame to show the tenons ror pins upn the- -endsof the slats, and the connecting-rod to which they are attached, and bywhich they are operated. Fig. 2 is a section, showing the` position ofthe end of the slats,and the manner of attaching the rod by whichv theyare operated. Fig. 3 is an enlarged detail view in verticalcross-section.

.A represents theftrame; B, the slats; G,- the tenons or pins; D, therod designed to connect and operate them; E, the knob attached to therod for the purpose of operating the saine. Fis an escutcheon or slot,through i which the knobstem passes for the purpse of attaching totherod. The groove 'Gr is made in the side of the frame to receivethe'tenons or pins of the slats andthe rod by Il represents the socketsinwhich the ends ofthe'tenons oper-y ate.. y

The followingis the operationof the same: The bead-strip J, through-whiehthe tenons or pins pass, and which form labearings on which theslats are pivoted, are attached bys'erew's, and`.may be taken out forthe purpose ot' taking the slats out, which may be done by unscrewingthe knob E from the rod 1 ),when

the Whole may be withdrawn from the groove G. The rod D is attached tothe pins or tenons C, like the attachment of the rods to the slats, inthe ordinary mode, where the attachment is made t) the edge Ioi' thesame by means of small wire staples. The ends of the pins G have a smallring or ferrule to holdv them from splitting, and t?) form a journal,and operate in the sockets H. The knob E is attached to the rod D bymeans of a screwtbread, and when the slats are adjusted, as required,the screw is operated by turning the knob and setting it first, andlocking the sla-ts in position.

Vrod D, and to operate in the sockets H.

The advantages of my invention are, that all outside attachment oi'rodsto the slats is dispensed with, leaving the surface smooth forvarnishing, and giving a much handsomer finish to the blind; and, in theincreased facility of locking slats in any desired position of openingor closing, or at any angle ot incli; nation. r

4Having thus described my invention, what I claim as new, and desire tosecure by Letiters Patent, is

The slats B, having long tenons C, incombination with the side grooves Gand sockets H, when the same are operated by means ot' the rod D, towhich rodthe't'enons are attached by blindstaples, and by the lock-knobE, orits equivalent, all constructed, arranged, and operatingsubstantially as described and shown, for the purposes set forth.v
